We will need more information to help.

Are you using DHCP or Static IP address?
Are you using a proxy server?

Cat you post the output of the following commands:

cat /etc/sysconfig/network-scripts/ifcfg-eth0
cat /etc/sysconfig/network
cat /etc/resolv.conf

That is a good start.

Your DNS is set to 192.168.0.1 which is a different subnet that your IP address.  

try this:

ping 192.168.0.1

and post the results.

Can you also post the config of the working box.

As the expert says, this box needs to be on the same network as the DNS + Gateway.

See an example of my box

[root@ewok ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth1
DEVICE=eth1
BROADCAST=172.16.255.255
IPADDR=172.16.1.46
NETMASK=255.255.0.0
NETWORK=172.16.0.0
GATEWAY=172.16.1.39
ONBOOT=yes
TYPE=Ethernet

Your current setup will work if you have a router in between your two networks, even then, you still need to change a few things.
